Agreeing with the ‘you are getting ahead of yourself’ posters.
Visiting a college because you happen to be in the area is one thing, planning summer holidays around it at this stage has more negatives than might be apparent.
-> Visiting different regions of the US is a great thing to do, but doing so to decide what region to attend college is putting the cart before the horse. Outside the extremes, the physical location/geography is the least of it. What will matter more is things such as rural/suburban/urban; contained campus or porous / integrated with a town/city; size of student body; relative presence of sports and/or greek life; access to / facilities for activities that are of particular interest to your D- and that’s before getting to the areas of relative academic strength and the level of selectivity. None of which is your D ready to address.
->Not to mention that it is really unlikely that a summer visit will give any idea of what it is like to live in a place- especially in places that have actual winters. Purdue in July is a terrible basis for deciding whether you would like to be at Purdue in January! (also, I am not sure if I am misunderstanding your statement, or if we have different ideas of weather, but when you say that your daughter is open to ‘colder’ weather, so anything from Georgia north is ok- do you know what Georgia weather is like? It’s not a place that I would think of as having cold weather. Get north of Maryland and you start getting ‘colder’ weather!)(ok, VT is in the mountains, so it can be colder as well).
-> College visits are not fun unless the student is really interested. You are planning on 2 summer vacations of it before she is even a sophomore in high school. If she isn’t dragging you to do this, it will not only not be happy, but she will burn out on it before it actually gets serious.
-> What a 12 or 13 year old thinks is absolutely everything she would love- or everything she would loathe- is likely to be different than what her 18 year old self will prioritize. What she remembers of the places will be through 12 or 13 year old eyes, which may set ideas in place that are counterproductive later.
True story: in the spring of Grade 11 my D1 had her college list finalized, including an ED that she was completely in love with. In October of Grade 12 she applied to 7 colleges- not one of which had been on her list in the spring. That’s how much she evolved in the 5-6 months between late Junior and early Senior year- now think how much your D is going to change over the next 5-6 years!
You asked for college suggestions, but I would suggest pushing your trips back. Do one summer after Grade 10 and one spring break of Grade 11. Let her grow up a bit, get more of a sense of herself and what what her interests, strengths and weaknesses are. Get some idea of what her options are likely to be - some idea of likely GPA range and test score range, both of which she will have then.
